Let's divide 170521 by 19
Our goal is to divide 170521 by 19.

Moving on to step 1:
19 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 19

Step 2:
17 divided by 19 is 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 19

Going ahead to step 3:
19 goes into 170 8 times with a remainder of 18.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 152 from 170 and we're left with 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 19

Advancing to step 4:
19 goes into 185 9 times with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 89.0
Deduct 171 from 185 and we're left with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 19

Going ahead to step 5:
When dividing 142 by 19, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 897.0
Subtract 133 from 142 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 19

On to step 6:
The number 19 fits into 91 4 times, leaving a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 8974.0
The remainder is 15 after subtracting 76 from 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
19 can be fit into 150 7 times, resulting in a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 8974.7
If we take 133 away from 150, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
When dividing 170 by 19, we get 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 8974.78
Deduct 152 from 170 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
19 goes into 180 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 8974.789
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
90 divided by 19 is 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 8974.7894
Subtracting 76 from 90 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
19 can be fit into 140 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 8974.78947
Subtracting 133 from 140 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
19 goes into 70 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 8974.789473
Subtracting 57 from 70 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 13:
130 divided by 19 is 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 8974.7894736
Deduct 114 from 130 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
160 divided by 19 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 8974.78947368
Subtract 152 from 160 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 8974.78947368 with a remaining 8e-09.
